WIPO Patent Application WO/2011/077483
Kind Code:
A1
Abstract:
Provided is a disc-type coil which ensures a sufficiently high value of a current that is made to flow in order to improve output. The disc-type coil is provided with: a disc-like insulating substrate (1); a conductor pattern (2) which is provided on the both surfaces of an insulating substrate (1) such that through hole lands (22, 23) are positioned on the outer circumferential side and the inner circumferential side of the insulating substrate (1) and the conductor pattern is alternately folded back on the both surfaces of the insulating substrate (1); and a through hole which is formed in the insulating substrate (1) and connects together the through hole lands (22, 23) of the conductor pattern (2). A plurality of through holes (6) are arranged in the radius direction (c) in the through hole land (23) on the inner circumferential side.
